HOSE-PIPE CLASP.

Specification of Letters Patent.

Patented J an. 8,1918.

Application filed September 17, 1917. Serial No. 191,822.

To all whom it may concern:

, Be it known that I, ARTHUR D. VVns'rooT'r, a citizen of the Dominionof Canada, residing at Porteau, in the Province of British loluinbia,Canada, have invented certain Improvements in HosePipe Clasps, of whichthe following is a specification.

preferably stamped from the sheet.

Figure 1 is bolt and adjacent are shaped and bent outward from the sidesThis invention relates to a hose-pipe clasp such as is used to secure ahose-pipe on the metal pipe or nipple to which it is connected. Theimprovements are directed to the provision of a flexible band in onepiece that will exercise its grip all-aroundthe circumference of thehose-pipe, and that will have a considerablerange between its maximumand minimum limits adapting it to variation in the diameter of the hosepipe to which it is applied.

These results are attained by forming the body of the band of thin sheetmetal with one end. shaped and threaded as a bolt to 1 Between the sideportions l and immediately adjacent them the thin metal of the claspcontacts with the band as shown in Figs. 1 and 2-, which rounding notonl enables the bolt end 3 to come closer to the periphery of thehose-pipe but imparts a measure of rigidity to the clasp in that sectorof it adjacent'the tightening connection of the two ends, and therebyenables the tightening action to be applied to the side of the hose pipeopposite the tightening connection.

The end 3 may be solid, forgedwiththe band Qor welded. to it, or theentire band may be stamped from sheet metal and, as shown in Figs. lvand 5, the edges ofthe end 3 may be rounded outward and closed on oneanother to form the round bolt form.

is rounded in cross section where it' A clasp so constructed isadaptable to 4 receive the tightening nut and its washer, is no stop tolimit the overlap of the end 3 and the other end shaped and outwardlypast the shoulder of the nutseat 4, so that turned to form a seat forthe nut and washer.

Those portions ofthe band which are ad-- jacent the bolt end and the nutseat respectively have a measure of rigidity imparted to them thatenables them to transmit the tension imposed by the bolt and nut .to theside ofthe clasp oppositethe connection.

The invention is particulazly described in the following specification,reference being made to the drawings by which'it is accompanied, inwhich:

a side elevation of the clasp in theplane of the circumference.

Fig. 2 "is a section on the line Fig.1.

Fig. 3 is a development of the band before flangingand bending.

Figs. 4 and 5 show the development and cross section of a modificationin one end of the hand. i

In these drawings 2 represents the body of the clasp which .is' of thinfiat metal and ne end 3 is formed and threaded as a tightening the otherend portions 4 form abracket seat tor the ,of theband to M of the boltand 3 and washer 5 and nut 6 leave an end 7 to project under the boltend and support the bracket seat.

' hose-pipe,

the limit of contraction. is the amount of thread provided on the end 3.The relatively rigid form of each end 3 of the clasp prevents the endsadjacent the connection from being bent inward on the hose-pipe as iscommon with many of the clasps at present on the market and it alsoenables the tightening tension to be transmitted more equably around theclasp.

,The clasp is convenient to use, as, being thoroughly. flexible and openon the outer side of the nut seat, it may be passed around the hose-pipeafter the the pipe to whichv it is connected.

'Havin now particularly vention, hereby declare that whatI claim as newand desire to ters Patent, is:

1. A hose-pipe clasp, stamped from thin sheet metal and bent to encirclethe hose;pipe, one end of said band being rounded and threaded toreceive a nut by which and adjacent the other end of the band its sideedges are sha ed and turned outward to. form a brackete seat for thenut, theedges of the band adjacent each end being in cross sectionrounded outwar to impart a measure of rigidity to the clasp adjacent theconnection'of the ends.
